Proof of Christianity

Yes, actually. Without evidence, one really would be justified in being skeptical of things that seem obvious to you or I.

They've likely heard about color all their lives. Is that evidence of color? In your following example you seem to think so. Why do you say they're without evidence?

Three boxes, each one a different color, but otherwise identical. Three objects with clear differences to touch so that the blind person could tell the difference. Have the blind person place the objects in the boxes, so that a sighted person can see which box contains which object. With the sighted person out of the room, have the blind person switch the positions of the boxes around without removing or altering the objects.

Since the boxes are different colors, the sighted person will be able to tell which box has which object despite the boxes being outwardly identical in every way except color. Now, the blind person might not know what color is, but we've definitely demonstrated an additional perceptual tool to them.

Or more simply, just ask different passersby what object a color is and get the same response. That's all you're doing above, as the blind person must take the first sighted person's word regarding the colors of the boxes.

So, testimony from other people is sufficient to establish existence.

This will blow you away.

The first thing to remember is that colour does not actually exist… at least not in any literal sense. Apples and fire engines are not red, the sky and sea are not blue, and no person is objectively "black" or "white".

What exists is light. Light is real.


You can measure it, hold it and count it (well … sort-of). But colour is not light. Colour is wholly manufactured by your brain.
